O(n) filter, applied to a predicate and a ByteString,
returns a ByteString containing those characters that satisfy the
predicate.
Filter this map by retaining only elements which values
satisfy a predicate.
Filter this set by retaining only elements satisfying a
predicate.
filter, applied to a predicate and a list,
returns the list of those elements that satisfy the predicate; i.e.,
filter p xs = [ x | x <- xs, p x]
>>> filter odd [1, 2, 3]
[1,3]
O(n). Filter all values that satisfy the predicate.
filter (> "a") (fromList [(5,"a"), (3,"b")]) == singleton 3 "b"
filter (> "x") (fromList [(5,"a"), (3,"b")]) == empty
filter (< "a") (fromList [(5,"a"), (3,"b")]) == empty
filter p xs removes any elements from
xs that
do not satisfy
p.
The
filter function takes a predicate
p
and a sequence
xs and returns a sequence of those elements
which satisfy the predicate.
O(n). Filter all elements that satisfy the predicate.
O(n) filter, applied to a predicate and a
Text,
returns a
Text containing those characters that satisfy the
predicate.
O(n) Drop elements that do not satisfy the predicate
O(n) Drop elements that do not satisfy the predicate
O(n) Drop elements that do not satisfy the predicate
O(n) Drop elements that do not satisfy the predicate
